## API Endpoints

The Underdog API supports Solana Mainnet-Beta and Solana Devnet. We recommend testing your implementation with our Devnet endpoint before moving to production. The Devnet endpoint is free to use while the Mainnet endpoint requires a subscription.

## Postman

If you'd like to test out our API endpoints using Postman, you can do so at our public [Underdog API workspace](https://www.postman.com/underdogprotocol/workspace/underdog-api/overview).  There are both Devnet and Mainnet API collections within Postman.&#x20;

To go in more depth on how to get started with our Postman workspace, follow the guide below.&#x20;
